This project aims to study the effect of microgravity on the break-up of liquids and formation droplets. The project proposes to experimentally study the way liquid filaments thin and breakup in the Bremen Drop Tower.mehr...

The main purpose of this project is to study the interactions between two bubble jets in microgravity. The designed experimental setup is based on an injection device that can control bubble generation frequency, size and velocity, injection angle and separation between jets. We have obtained numerous on ground results on both individual as well as collective behavior of bubbles.mehr...

When a liquid droplet touches a porous surface, its penetration is first inhibited by a short inertial phase, followed by a longer regime dominated by viscosity. Although the inertial phase governs the dynamics of penetration, it is nearly impossible to observe it on Earth, as drops must be very small to avoid being deformed by gravity.mehr...

In many situations, granular systems subjected to external agitation have a tendency to segregate, rather than to mix. This phenomenon is of enormous importance in industrial applications. When mixtures of particles differing in size, shape or material properties are agitated, a variety of pattern formation phenomena are observed (e.g. I. Aranson & L. Tsimring, “Granular Patterns”, Oxford University Press, 2009).mehr...

Plants have evolved under the constant force of gravity and its presence strongly influences growth and development of plants. For this reason, changes in gravitational field strength, both hypergravity and microgravity, can be considered as a source of stress that is initially perceived at root level and transmitted by signalling chains to the other organs in order to adapt plant physiology to these changes.mehr...

FELDs is a technology demonstrator that tests the performance of an innovative tethered soft docking system. Our experiment aims to understand the low gravity behavior of the proposed technology by studying the dynamic response of the capture system and its effects on the impacted spacecraft.mehr...

This experiment aims on the investigation of the behaviour of granular anisotropic gases in microgravity. Anisotropic granular gases are encountered in a number of situations - in avalanches, sandstorms, dust devils, the formation and motion of dunes, planetary rings, and the asteroid belt, to name a few.mehr...

Light from the Sun or a laser beam can be used to transfer momentum to matter and displace low-mass objects. Space agencies have successfully tested the solar sail technology for low-Earth orbit applications, navigation control, and Solar System exploration, with IKAROS being the first demonstration of spacecraft with solar sail as primary propulsion system in 2010.mehr...

The Portuguese research group who was elected for the "Drop Your Thesis" campaign came to the drop tower with a study on Polymer Dispersed Liquid Crystal (PDLC) materials obtained from polymerizations in 0g and 1g with three different liquid crystals (LCs) was made.mehr...

STAR (Space Tether Automatic Retrieval) is an experiment carried on by a team of engineering students of the University of Padova. Its main objective is to develop and validate the technology used to build a new concept for a space tether deployer with retrieval capability.mehr...

Ferrofluids are carrier liquids in which magnetic nanoparticles are suspended. The behaviour of ferrofluids in microgravity is largely unexplored because experiments in microgravity are expensive and the access to associated facilities is limited.mehr...
